How do I apply for Portuguese nationality?

AIMA · IRN · Residence & nationality

• The application is made to the IRN (Institute of Registries and Notaries) — in person at the nationality counters and Loja do Cidadão (Citizen Shop), or by mail; lawyers and solicitors can submit it online.
• The requirements depend on the route: legal residence in Portugal for the period required by law, marriage or partnership with a Portuguese citizen, ancestry, among others.
• For the residence route, you usually need to prove Portuguese language knowledge and an effective connection to the community.
• Follow the process using the number assigned to you — decision times can be long.
